Police arrest five in Sydney gun raids

Police in Sydney's south-west have raided 10 homes and taken five people into custody in an operation this morning against illegal firearms.

Over 200 police officers took part in the dawn raids as part of Operation Taskforce Gain.

Three handguns and ammunition were discovered in homes at Hinchinbrook and Prestons.

Police are still searching for three military-style weapons they believe were used in a shooting incident at Condell Park in August in which dozens of rounds of ammunition were fired into a home.

The Assistant Commissioner of State Crime Command, Graeme Morgan, says today's raids are part of an ongoing fight against gun crime.

"This...is the most recent undertaking of Taskforce Gain," he said.

"Those results, including those of this morning, are a demonstration of the capacity of the New South Wales police to deal with the serious crime issues in the south-western suburbs of Sydney and should lend encouragement to all people who have any information at all to contact Taskforce Gain."
